Explorer: Background images underneath borders

Applies to Explorer Windows and Mac.

Explorer positions a background-image underneath the border
of the element.

Therefore it's impossible to get the position of a background image in an element with a border correct
in all browsers. No problem, we can use nested elements for defining images and borders separately.

Test case

The background image should be wholly visible besides the border of the items. In Explorer it's partially
obscured by the border.
